I would take the vacuum and main fuel lines off and just, pardon the expression, **** on it to see if the fuel will start to come out from the petcock outlet. Also check the position of the valve to make sure it is in the "on" or "res" and not "off". Duh. It happens.
If that doesn't get it then the petcock needs a rebuild. If the fuel line or vacuum line is clogged or the carb floats are stuck closed you will also get no fuel. Check it all out with patience and curiosity. It's an easy fix.

Suzuki 750 Katana Hoses?

Hi, Alexander always check your service manual for proper routing, PVC type valves, and vent lines allow the following components to breathe freely:
1. Gas caps.
2. Gas tanks.
3. Carburetors.
4. Lead acid batteries.
5. Evap canisters.
6. Engine crankcases.
7. Rocker boxes.
8. Transmissions.
Numbers 2-3-4 have vent lines that are routed directly to the ground usually 2" below the lowest part of the frame and loosely secured with stanchions/stand-offs or tie wraps. These lines have minimal curves and their ends do not attach to anything "WARNING" these lines should be inspected at every maintenance service for end clogging or closure pinching or kinking or missing altogether.
Failure to properly inspect and maintain vent lines may lead to:
1. Gas tank implosion.
2. Improper float levels.
3. Batteries exploding.
4. Blown crankcase and transmission seals.
5. Air cleaner oil saturation.

I have a 1986 suzuki 650 savage the carb seems to have a problem. It started flooding gas coming out the over flow. I took it off and took the float cover off and replaced the needle needle set and float....

Yea these carbs can be a real pain sometimes to get right. First thing you need to do is varify the float seat is working and totally stopping all fuel flow.... and all the jets, main, pilot and choke circuit are absolutely clean. Bench test the float needle valve by connecting a hose to the carb fuel line nipple and letting gas gravity feed as it would in a run position. if it tests ok, remount it on the bike...
i'm guessing you have a vacuum petcock on this year model? If you do, it needs to be inspected.
In the "on" position you should have no gas flow coming through the petcock, In the "prime" position it free flows. If there is a hole in the diaphram the engine will **** gas and not air (vacuum) through the hose and it will flood. If you don't have a vacuum line on your petcock then it is a different kind. Be sure to check your crankcase, it could be way past full with gas that has entered, dont start your engine like that...drain it all out. make sure the air filter is dry. You will have to replace the spark plugs...a gas soaked plug won't fire.
Good luck, i hope this helps.

The damping oil seals (dust seals) may just be worn and require replacement. If this is the case then £10-£15 for a pair and 2hours work (or £30-£40 for labour and parts if done by a mechanic).

Hi I have bought a 1985 700 maxim watercooled it has been sitting for appr 2 years today I took carbs out, disassembled them, cleaned them w carb cleaner and put them back in in addition to that I...

If I understand "the petcock was in prime position and it eventually quit dripping."
Prime = on
Sound like the needle rubber was hard and after a while they soften up enough to cut off the fuel.
Keep an eye on it and ride safe.

How do i adjust or tune up my carb on a 1985 suzuki gs 550 l runs but the has to be choked out

If it is running like that with new fuel the problem could be plugged idle jet circuits. The carburetors will have to be removed, opened and cleaned. You will need compressed air for this job. Good idea to replace all 'O'rings inside carb at this time.

How do I rebuild the petcock for a 1985 suzuki gs700es?

You should be able to get a gasket kick from either a dealer or out of Dennis Kirk, Parts Unlimited, Tucker Rocky. It should only be about 4 screws to remove the insides. Just be careful because there is a spring in there.

85 gs700es. replaced petcock but not getting any gas to the crabs. anyone help?

assuming your fuel lines to the carb are clear, I would think that the float is probably stuck. If you tap lightly on the float bowl it may unstick. Just use the back of a screwdriver or something like that. Just don't dent the cover. If that doesn't do it then you may have to remove the cover and clean it out.
